The Glide build is known to be touchy. Gentoo users will want to say export WANT_AUTOMAKE=1.7 before running chores.3dfx. If this branch doesn't build for you, you may have better luck by checking out the Glide trunk by omitting -r glide-devel-branch from the cvs command. You'll need nasm installed in order to get the optimized assembly code.

Good luck.

Future work

Glide is very fragile, and using it as a wrapper layer means that the tdfx driver doesn't look much like the other drivers at the source code level. This makes the tdfx driver rather hard to maintain. We should rewrite it to talk to the hardware directly.
